Method for manufacturing cycloalkanol and/or cycloalkanone |
(57) The object of the present invention is to provide a method for manufacturing cycloalkanol
and/or cycloalkanone with favorable selectivity coefficient by oxidizing cycloalkane
with favorable degree of conversion.
In the present invention, cycloalkane is oxidized with oxygen in the presence of a
catalyst wherein gold is supported on ceric oxide. Said oxidation is preferably performed
in the presence of a free-radical initiator and the free-radical initiator is preferably
2,2'-azobis(isobutyronitrile).
